AUTOMATIC ADVERTISING DEVICE.

SPECIFICATION forming part of Letters Patent No. 487,563, dated December 6, 1892.

Apnlication filed February 27, 1892. Serial No. 423,072. (No model.) I

To all whom it may concern.-

Be it known that I, THEODORE BENJAMIN HAFERTEP, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Automatic Advertising Devices, of which the following is a full, clear, and exact description.

This invention relates to a class of advertising devices that are exhibited in public conveyances, and has for its object to produce a simple exhibitor that will be adapted to change the location of advertisements attached to it and by a progressive movement of the latter attract public attention thereto.

To this end my invention consists in the peculiar construction of parts and their combination, as is hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation, partly in section, of a railway-car, with the improvement in position and adapted to receive motion from thecar-axle. Fig. 2 is a transverse section near one end of the car, showing the up: per portion of the operating mechanism of the exhibitor; and Fig. 3 is a transverse section of parts, taken on the line 3 3 in Fig. 1, showing the supports for the endless exhibitor-band and the latter in position, other portions of the device being removed.

As before indicated, the improvement consists, essentially, of an elongated endless band of flexible material, supported to move longitudinally on a bracket-frame that projects from the side or roof inside of a vehicle, the bandhaving advertisementsin series mounted upon it, so as to be conspicuously displayed when they are brought into View by a longitudinal movement of the band.

In the drawings, a a are two fiat bars of a proper length, which are secured upon the bracket-arms b, which project at proper points from the side wall or roof of a car or other vehicle inside of the same, the bars being held parallel thereby. Between the frame-bars a at their front and rear edges similar guideplates 0 are secured, these extending nearly to the ends of the bars whereon they are affixed. The guide-plates have their edges return-bent, as at 0', so as to produce a keeperflange on each edge, suitably removed from the main portion Which serves as a guide and support for the exhibitor-band 01.

At each end of the parallel bars a a small drum e is pivotally sustained between them, which drums are provided with radial flanges at their ends. The flexible endless band at is located upon the drums e and extends along each guide-plate c, the flanges c of which hook over the band at opposite edges, and thus loosely retainit in place upon the guideplates.

Upon the outer surface of the band d, which preferably is made of a length to extend nearly the length of the vehicle-body, such as a car A, there are advertisements imprinted or secured which'may occupy the entire area of the band, that will be exposed as the band is slowly rotated and progressively moved upon its supports.

A preferred means for actuating the endless exhibitor-band d is shown, and consists of a continuous belt g. Said belt is placed upon a flanged pulley h, that is affixed to the projected shaft, whereon a drum 6 at one end of the bar a is secured, and thereby adapted to rotate. From the pulley h the belt 9 is later ally extended to engage two idler-pulleys t', that are pivotally sustained in vertical planes upon the end wall of the car-body. Below the car-body A, in the same vertical planes with the pulleys 1', similar pulleys m are pivotally supported, the endless belt 9 having an engagement therewith. Preferably the idlerpulleys t' and m are furnished with flanges at the edges, which retain the belt from displacement. Upon the car-axle B, having the usual wheels B, supported to rotate on the car A, a flanged pulley-wheel n is secured, whereon the endless belt 9 is mounted, and to assure a proper contact between the pulley and belt the latter may be crossed in the portion that lies between the idler'pulleys 'm and pulley n, as shown in Fig. 1. Above the flanged wheel n a small presser-wheel 0 is supported to rotate in vertical alignment, and sufficiently near to said wheel so as to prevent the belt g from slipping or climbing over either flange on the pulley-wheel.

In operation when the car A is moved in either direction the rotation of the axle B will transmit motion through the belt 9 to theendless band cl, so that the latter will be moved as a panorama, and by its longitudinal progression bring into view advertisements that are on concealed portions of the endless band, and, if desired, pictures of any kind may be alternated with the advertisements, so as to attract attention to the moving exhibit.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentp I p 1. All advertising device comprising an elongated stationary frame. within a wheeled vehicle, guide-plates extending lengthwise of the frame and having return-bent edges, an endless band supported to move on the guide plates between the bent edges and around the frame, and an endless belt adapted to receive motion from an axle of the vehicle andtransmit it to the band and prdgressivelyinove it, Substantially as described, Y w

2. The combination, with a wheeled vehicle, an axle rotatable thereon, a flanged pulley onthe'axle,'and an endless belt'engaging'said pulley, ofa stationary elongated frame with the vehicle, comprising two parallel bars, guide-plates between on the edges of the bars, and return-bent flangeson side edges of said plates, bracket-arms supporting the frame,a flanged drum rotatable between the parallel 3. Thecombination, with a wheeled vehicle, an axle supported to rotate thereon, a flanged pulley on the axle, and a presser-wheel rotatable on the vehicle above the pulley on the axle, of an elongated frame within the vehicle .held projected therefrom longitudinally, comprising two parallel bars, opposite guideplates secured near the edges of the bars and having return-bent flangespn side edges, a flanged drum 1 'otatable between the parallel bars at c nd, 0 ;v the f e he a ha o one drum extending below the frame, ajflanged pulley on said projection of "the shaft, two idler-pulleys above and twoidler-pnlleys below on the end wall o t 'the vehicle, an endless belt engaging all the pnlleys, and ZLYl Q IIQl lGSS band mountedon the drums loosely engaging the guide plate's and their flanges, substantially as described.
